I need to repair an existing sprinkler system and run all new lines in another area. I am not going to change anything just mimic the existing piping. Can i do it in house or does this have to be done by certified sprinkler pipe fitter. Facility is in NJ
I have had in stock for years Micarta or Garolite which i use as a bearing in a underwater agitator with a bronze sleeve. I have used up the last of my stock and am not sure what grade to use.
